You also said in your OP that you were in a hole from your sports betting too – and that you turned to blackjack to get you out of it. So what happens next time you are in a hole? Will you walk away from sports betting never to return? My guess is you will try and find some other way to keep betting – that is the hold that this addiction has on us.
So my advice would be to look at other threads on this forum. You need to stop all forms of gambling, as one can easily lead to another. Ban yourself from places where you do and could gamble (including on-line.) Hand control of your finances to a trusted family member or friend – or if that is not possible put barriers here so you cannot just “put a bet on” when your resolve is weak. Get good support for yourself, through GA (Gamblers’ Anonymous) or some other self help group / counseling. Keep yourself occupied with some non-gambling activity, again there are threads which will give you some ideas of what you can do.
Sports betting is a difficult one – because many people want to enjoy watching their sport whilst they are recovering from gambling – but that causes so many triggers. Some of the sports bettors on here may be able to offer advice on how to deal with this – but taking part in a non-competitive sport seems to work for some. I wish you well.
